[glyf] Don't accept gids higher than maxp's glyphs number
...
This specially becomes concerning on sub-components where a gvar table
that is sanitized using maxp's glyphs number overflows when a high gid
accepted here goes to it, maybe an additional check can be put there
also, this however feels to be enough.

This doesn't imply the the design is good or stable just is better
to not fail due to null quad-to callback so as our quad-cubic curves
translation is currently table limited which can be revisited anytime.
